ABSTRACT:
A pulse-width doubler is disclosed as comprising a bistable multivibrator ving a first input, a second input, and an output, for producing a first signal at the output thereof in response to a predetermined second signal being supplied to the first input thereof and for producing a third signal that is different from said first signal at the output thereof in response to a predetermined fourth signal being supplied to the second input thereof. A digital counter and storer, having an up-count input, a down-count input, a zero reset input, and an output, with the output thereof connected to the aforesaid second input of said first and third signals producing means, for up-counting the pulses of a pulsed fifth signal being supplied to the up-count input thereof, for down-counting the pulses of said up-counted pulses in response to a pulsed fixed signal being supplied to the down-count input thereof, and for producing the aforesaid fourth signal at the output thereof immediately after the aforesaid down-counting of said up-counted pulses have been completed. A steering generator, having an input and a pair of outputs, with the input thereof connected for response to the aforesaid predetermined second signal and with the pair of outputs thereof respectively connected to the up-count and down-count inputs of the aforesaid up-counting and down-counting signal counter and storer, for respectively generating and supplying said pulse fifth and sixth signals thereto in response to said first and third signals. A reset monostable multivibrator, having an input connected for response to said second signal and an output connected to the zero reset input of said up and down pulsed counter and storer for supplying a zero reset signal thereto in immediate response to said second signal.
